You should still be able to buy PDFs of the individual Dungeon magazines (where the AP originally was published) from Paizo. The only thing to remember is that SCAP started in 3.0, while the hardcover was revised (rules-wise and probably story-wise too) for 3.5.

I own both and can confirm that both the HC and the early (3.0) adventures are slightly different, let alone the addition of an additional adventure (Drakthar's Way).

I don't think the early adventures were harmed much if at all by the switch, other than slight changes to a few spells (re: haste) and a few monsters changed.

I ran (up to test of the smoking eye) IRL recently, before a TPK and it was great. The problem was the cast of characters kept changing so fast it was difficult to keep the story straight. Sadly, my employer has changed my schedule, limiting my RL gaming to virtually nil.

I ran a PbP up to the beginning of the Zenith Trajectory, but ran out of steam due to several RL changes that really hurt my time online. It's just now (2 years later) starting to come back to where I can do stuff online. Yeah... that's frustrating.

I definitely like the PbP format better for this AP for some reason. I can't figure out why, but it just hits me better that way.

Actually, WotC is sorta freeing up their products for PDF on Drive Thru/RPG Now. I agree that this book would make a fine addition to anyone's RPG library, especially since the Paizo logo is plastered on it rather than just the WotC logo. Did whoever buy first rights, all rights, or what? And in this day of electronic editions would a battle ensue (notice the word "sue" here) over who exactly has the E-Rights? It wouldn't take much effort to clean out the TSR/WotC refences and publish it as a straight Pathfinder book...

WotC has all the rights, as they own Dungeon magazine.

Paizo had to ask WotC for permission to make the hardcover, which was granted. (My understanding is that Paizo would also have liked to make Age of Worms and Savage Tide hardcovers, but WotC only gave permission for Shackled City - and also the Dragon Compendium and Monster Ecologies; I'm not sure if there was anything else from the magazines published as a book.)

Paizo produced it under a license from WotC. The license ended, I know Paizo cant reprint or put out pdfs without a new agreement with WotC. I suspect the reverse may be true as well for the hardcover compilation, WotC might not be able to unilaterally reprint it. Vic would be the one to ask.
